amt o. Blom, Springfield, Mass, assignor t Bigelow-Sanford Carpet U0.Inc, Thompson j I .ville, Conn. a corporation of MassachusettsApplication October 21, 1935, Serial No. .5.8 8 31 01am; (01. 28-555).

This invention relates to setting or winding frames employed for windingyarn on spools to be used in the weaving of Axrriinster rugs, and itparticularly pertains to improvements in the construction of machines ofthat character whereby to obtain a more uniform and more accuratelymeasured winding of the yarn on the spools thanhas. been obtainableheretofore.

In the winding of spools on such frames it is essential thatsubstantially the same predetermined amount of yarnv be wound on all ofthe spools," both overwound and underwound, and I have foundthat thatresult can he accom-.

plished by providing a tension on the yarn adjacent the spool .as it isbeing wound which is not only ofitpproxirnaizely the same predeterminedamount for all spools being wound, both overwound and underwound, butwhich is also substantially unvarying as the spools fill with yarn.. Thepreferred'form of apparatus and method embodying my invention insuresthe proper substantially unvarying tension around the spool bypositioning the threewinding rolls at substantially equal distancesaround the. pee

" riphery of the spool, whic rolls are yieldingly pressed thereagainstand are rotated at a predetermined differential, in speed to exert adrag on the yarn at the points of contact there with. .Ifhepredetermined amount of tension which is thereby. produced is preservedas the spool fillsby maintaining thesubstantially equidistantrelationship of the spools while permitting a gradual yieldingdivergence of the rolls as required to accommodate-the growth of yarn on"the spool.

The foregoing characteristics of my apparatus are preserved forbothoverwindingand under- Winding and in that manner I insure an equal.

amount of tension and hence a uniformity in the amount of yarn wound ineither direction.

Accuracy of measurement of the yarn Wound. on the spool is not dependentsolely upon the accuracy of the Winding operation of the setting frame,but also depends upon the manual operations'oi drawing off the yarn atthe completion of the winding of one spool, clamping up the ends of theyarn strands on the wound spool,v and overlapping the severed endsofyarn around Here tof ore, inaccuracies have arisen through the failthenext succeeding spool to he wound.

By way of introduction to the description of the preferred embodiment ofmy invention, reference is made to Figs. 1-6 inclusive wherein I havediagrammatically illustrated the disposition and mode of operation ofthe winding rolls of one embodimentof my invention.

As indicated diagrammatically in Fig. l, the yarn l is fed, asiscustomary, from the bobbins 2 comprising the creel 3, through a combingreed 4 to a pair of idler rolls 5 and 6 which are associated withcounting mechanism for-measuring the yarn and which also produce acertain tension on the yarn as it passes through a second reed H], overan idler roll I! and thence to the spool 52 on which it is being wound.Movement of the yarn from the creel 3 through the aforesaid mechanismand to the spool i2 is effected by three winding rolls 20, 2| and 22which are disposed in peripheral engagement with the spool l2 and theyarn wound thereon.

As indicated in Fig. 2, wherein is shown the position of the windingrolls 20, 2| and 22 at the beginning of the winding operation, the rollsare then disposed at equal intervals around the periphery of the spool|2. As the spool l2 fills with yarn, I preserve the equidistantrelationship of the rolls while permitting'divergence of the rolls toaccommodate the growth of yarn, until the end of the winding operationwhen the rolls are positioned as illustrated at 20B, 29B and 22B of Fig.'3. To preserve this equidistant relationship at all stages of thewinding, I may mount the winding rolls each in sliding bearingsextending radially from the axis of the spool l2, but I have found thatfor simplicity of construction, one of the rolls, such for example asroll 2|, may be mounted in stationary bearings and the rolls 20 and 22may be mounted in bearings carried by crank arms which are pivoted tothe frame of the machine and are adapted to swing in arcs about theirpivots to accommodate the growth of yarn on the spool. This constructionI have diagram matically illustrated in Fig. 4 wherein the roll 20 isindicated as mounted in a bearing which swings about the point 20' as apivot and the roll 22 is mounted ina hearing which swings about thepivot 22'. The disposition of the pivots 20' and 22' and the lengthofthe radii to the axes of the rolls Ziland 22 can readily be chosen toprovide the equidistant relationship of the rolls 20 and 22 relative toeach other andto the stationary roll 2| during the entire windingoperation, including the intermediate positions of the rolls 2|] and 22and I have found that in a machine constructed on that principle, theaxis of the spool l2 may move away from the stationary spool 2| during Ithe winding operation in a path which describes an are, as indicated at32. I

To provide access to the spool |2 for its removal at the completion ofthe winding operation and for'insertion of a new spool, the upper roll22 is adapted to be swung further about the pivot 22 to the positionindicated diagrammatically at 22C.

As stated above, I have found that the proper tension of the yarndirectly at the periphery of the spool I2 on which it is being wound maybe effected by a differential of speeds between the three equally spacedwinding rolls in engagement with the yarn, whereby to exert a drag onthe yarn at the points of contact of the winding rolls. As indicateddiagrammatically in Fig. 5, wherein I have shown, by arrows, thedirection of rotation of the rolls 20, 2| and 22 for the overwindingoperation, I provide this differential of speed and resultant frictionaldrag on the yarn by making the roll 22, which is the initial roll withwhich the yarn comes in contact as it enters the spool, and idle roll,and by making the rolls 20 and 2| driven rolls with the roll 2|rotated'at slightly greater peripheral speed than that of. the roll 20.To insure equality in the amount of yarn wound in the underwound andoverwound directions of rotation, I preserve this same relationship forthe underwinding, whereby, when the direction of rotation of the rollsis reversed, as indicated by arrows in Fig. 6, the roll 2| with whichthe yarn initially comes into engagement is an idle roll and the rolls20 and 22 are driven rolls with the roll 22 rotating at a speed which isslightly greater than that of the roll 20.

Referring now to Figs. 7 and 8 I will describe first the generalassembly of my novel setting frame. As there indicated, the creel 3 issupported at the proper elevationat what I shall designate as the rearof the setting frame. The

frame of the setting frame has the two vertically extending side members50 and 5| in-which are mounted the winding rolls 20, 2| and 22 in amanner to be described more in detail hereafter. An

electric motor 52 or other suitable power source 7 is provided fordriving the winding rolls in either their overwinding or underwindingdirections of winding rolls is also adapted to move the winding rolls 22from its winding position to its open position indicated at 22C toprovide access for removal of the spool |2 which has been wound andinsertion of a new spool in winding position.

The side frame members 50 and 5| also rotatably support the measuringrolls 5 and 6, the bottom roll 6 being fixed in positionand the top roll5 being mounted in movable bearings 600 which may be elevated or loweredin the side slots 55 in the frame members 50 and 5|.

To describe first the mountings of the rolls 20 and 22 whereby they maybe moved toward and away from the spool |2the winding roll 22 (Figs. 9and 11) is carried on the shaft 80 which is mounted at both ends inbearings carried by pivoted housings El and 82 rotatably mounted in theside frame members 50 and 5|. The details of these mounting elements areillustrated in Fig.

12 in which are shown the bearings 83. and 84 carrying the ends of shaft80 and in turn carried by the pivoted housings BI and 82 respectively.Both housings are constructed in the general form of a crank, thehousing 8| having a vertically rising crank arm portion 90 integral withand extending from a hub 92 journalled in the frame 50 of the machine.The hub 92 is reduced in cross-section at 93 to receive a gear 94 .fixedto As will appear, the

to, I

the hub 92 bymeans of the dowel 95 and screw 96 passing through alignedholes in the gear 94 and hub 92. A similar crank housing to bedescribed, is provided for the bearing 84 on the opposite end of shaft89 and it is apparent that as a result of this construction, rotation ofthe gear 94 rotates the hub 92, thereby rotating the crank arm 90 of thehousing 8! and swinging the roll 22 about the axis of hub 92.

The gear 9-; is one element in a train of gears which I shall refer toas the pressure gears, rotated pneumatically by a piston in cylinder. H3(Fig. 8) whereby a yielding pressure of the driving roll 22 (and, aswill appear, also the driving roll 253 against the spool) is effected.

Referring now to Figs. 9 and 12, the aforesaid pressure gear 94 mesheswith idler gear I05, rotatably mounted on the stud shaft I06 fixed inthe frame member 58. The gear I meshes with the gear 98 which isrotatably mounted on the shaft 59 (Fig, 13) and in turn meshes with thegear segment 99 keyed to the shaft NH.

The shaft IilI, as indicated in Figs. 8 and 11,

extends across the machine and has bearings in side frames 55) and 5|.Intermediate its length the shaft II] I, carries rigidly fixed to it thepinion 'I I6 which meshes with the rackIII carried by the plunger IIZwhich is pneumaticallyelevated and depressed in the cylinder H3 in amanner to be described more in detail hereinafter. v

The shaft IIiI carries rigidly secured to its extremity opposite to thatcarrying the gear segment 98 and adjacent the frame 5| of the machine,(Fig. 11) a second segment IZll identical with the segment 99. Thesegment I253 is connected, through a second set of pressure gearsmounted adjacent the frame 5I of the machine,

to crank housings carrying the opposite ends ofment i253 are illustratedin Fig. of the drawings and as there shown, the segment .IZil fixed toshaft Elli meshes with the gear I2I secured to a hub I22 of a crankhousingcarrying the shaft of the roll in a manner to be describedhereinafter. The gear I2I mieshes with an idler I23 rotatably mounted onthe stud shaft I2- l projecting from the frame SI of the machine (seealso Fig. 12). gear 525 which, as indicated in Fig. .12, is fixed, bymeans of the dowel and screw l2! and I28, on the hub 53 3suitablyjournalled in the frame El and integral with the crank housing82 carrying the bearing 84 for the right hand end of the shaft 8%. i

The trains of pressure gears on both sides of the machine havecorresponding gears of'equal pitch diameters and number of teeth and, itwill be apparent from the above description that elevation anddepression of the plunger I52 in the cylinder IIf-l will move the roll22 in either a clockwise or counter-clockwise direction, as viewed fromeither side, dependingupon whether the plunger II2is elevatedordepressed and will apply an equal amount of pressure from both ends ofthe roll, pressing it yieldingly against the spool I2. u

To describe now the pressure gears which swing the bearings of the roll28, that roll is carried. by a shaft t il} (Fig. 13) which has thebearing I in the arm I 52 of a crank housing, the hub I43 I of which isjournalled in the. framememberfill of The idler I23 meshes in turn withthe the'machine, and carries the aforesaid pressure gear 98. Thepressure gear 98 isnot fixed to the hub I43 as was the correspondinggear 93 associated with the roll 22, but carries a pin I5I, the enlargedend I 52 of which has. a sliding fit in the slot I 53 of the hub I43,which slot, as indicated in The gear til is connected, as describedabove, with the gear segment 99 (Fig. 9) fixed on the pneumaticallyrotated shaft NH. 1 On the opposite side of the roll 20, from that justdescribed, the shaft ltd has a bearing I60 inthe crank housing IGIwhichhas a hub I22 iournalled in the frame iii of the machine, which hubcarries the gear Ilil. The gear I2I is. connected to the hub I22 by apin I63 having a head Ifie working in an arcuate slot I65 identical inconstruction and function with the arcuate slot I558 in the hub I63 onthe opposite side of the machine. The gear 52!, as statedabove, mesheswith the segment 520 (Fig. 10) which is fixed to the end ofpneumatically rotated shaft I0 I.

Referring now to Fig. 11, rotation of shaft IBI is effected by means ofpinion IIO fixed to shaft illl and meshing with rack I I I carried bypiston red I it elevated and depressed by a double acting piston QIi'iilsliding in the cylinder H3. cates a threeway valve adapted selectivelyto elevate or depress the piston 230 pneumatically or to assume arelease position in which the piston 239 can be elevated or depressed atwill whereby the rolls 2i} and 22 can be manually swung about theirpivots.

The valve 2!): communicates at 202 with a sup- 1 2M indiof the cylinderI I3, above the piston 2M, and the pipe 206 leading to the port 20]brings the valve into communication with the lower part. of the cylinderI I3 below the piston 290. It will be noted that the ports 2&5 and 297are diametrically op-' posite each other on a diameter which isperpendicular to the diameter along which the ports 292. and. 263are inalignment. The valve 25)! is fitted with a suitable hand lever, notshown, whereby it may assume the three positions indicated in Figs. 11,1'7 and 18.

The valve 2M is drilled to provide a conduit 2m extending diametricallyacross the valve 2M, which conduit, when disposed in thepositionindicated in 11, brings the upper and. lower ends of thecylinder I it into communication with each other whereby the pistonBibi! may beelevated or depressed at will and the rolls 20 and 22 may bemanually swung about their pivots.

The valve 20% is also drilled to provide two vide an angular conduit2I3, each end of which I is disposed at a distance of around thecircumference of the valve EIII from the nearest em of conduit 210.

The valve which is constructed as above described, if rotated to theposition indicated in Fig. 1'7, disposes the connecting conduits 2H and2I2 in position to bring the port 292 into communication with the port20'! whereby compressed air entering the port 202 will be conductedthrough the pipe 296 tothe lower end of the cylinder II3, therebyelevating the piston 200. At the same time the upper end of the cylinderH3, above the piston 29!], is in communication with the .exhaust pipe293 as a result of the position assumed by the conduit 2|3 which bringsthe port 295 into communication with the exhaust port 293. Thiselevation of the piston H2 will cause clockwise rotation of the segment39, as indicated by the arrow in 9, which will cause counter-clockwiserotation of the gear 98 which meshes with the segment 99. Thiscounter-clockwiserotation of the gear 98 will cause the end I52 of pinl5| carried by the gear 98 (Fig. 16) to abut the end I54 of the slot I53in the hub I43 to swing roll 20 to its position indicated in Fig. 16.The roll 22 (Fig. 9) will also swing in a counter-clockwise directionabout the axis of the shaft I00 as a result of gear train 98, I95 and94. It will be observed that this direction of swing of the rolls 29 and22 urges those rolls into engagement with the spool I2. This is therunning position of the rolls 29 and 22 for winding yarn on spool I2 andit will be noted that as the spool I2 fills with yarn the rolls 26 and22, which yieldingly press against the spool, are swung away from.eachother while maintaining their equidistant spacing about theperiphery of the spool (Fig. 4). This swinging movement causes a graduallowering of piston 200 against the pressure in cylinder H3.

After the spool I2 has been wound, it is desirable, as stated above, toswing the top roll 22v away from the spool I2 and to the positionindicated. at 22C in Figs. 4 and 9, whereby to permit removal ofthewound spool and insertion of an empty spool.

To effect this movement the valve 29! is now shifted to the positionillustrated in Fig. 18 and in that position the port 292 communicatingwith the compressed air supply is brought into communication with theport 205 and thence to the upper end of the cylinder H3 at the same timethat the lower end of the cylinder is exhausted through the port 201 nowin communication with the port 293 through the valve conduit 2I3. Theresultant depression of the piston 290 causes a counter-clockwiserotation of the gear segment 99 in the direction opposite to thatindicated by the arrow in Fig. 9 which causes a clockwise rotation ofthe gear 98.

This rotation of the gear 98 (Fig. 16) moves the pin end I52 in aclockwise direction and as a result of the weight of roll 20, the endI54 of the slot follows the pin end I52 until the roll 20 comes to restagainst a convenient stop IlIB, after which swinging of roll 2!] stops,while permitting the gear 98 to, rotate approximately one-quarterrevolution in a clockwise direction. This amount of rotation of the gear98 is sufiicient, however, to rotate gear 94 in a clockwise direction inan amount sufficient toretract roll 22 to its 220 position, therebyproviding the desired access to the spool I2.

The rolls 2!], 2| and 22 are each power-driven by certain mechanism nowto be described. It

will be recalled that the rolls are tobe rotated in one direction foroverwinding spools and in the opposite direction for underwinding spoolsand that in the overwound direction (Fig. 5) the roll 22 is, in mypreferred embodiment, an idler roll and the rolls 2B and 2| are drivenat different relative speeds, whereas in the underwound direction (Fig.6) the roll 2| is an idler and the rolls 2!! and 22 are driven in adirection opposite to that for the overwinding and at the same speeds asthe rolls 2B and 2| respectively were driven in the overwindingdirection. These rolls are driven from a motor 52 (Fig. 7) which hasreversibleconnections later to be described.

As indicated in Fig. 11, the motor 52 has an elongated shaft 63 whichincludes clutch 64, on the end of which shaft the pinion 10 is rigidlymounted. The pinion 10, which is the initial gear in a train of gearswhich I shall refer to as the power gears, meshes with an idler 65 (seealso Fig. 9) fixed to the stud shaft 66 rotatably mounted in a suitablebearing in the frame member Stud shaft 66 also carries rigidly fixed toit pinion 61 which meshes with a gear 68 fixed on the aforesaid shaft 69in front of the gear 98 (see also Fig. 13). The gear 68 meshes with thegear 72 which is connected to the shaft 69 with which the roll 2| isintegral, by means of a oneway clutch illustrated in Figs. 14 and 15.

The shaft 6|! carries fixed to it at the end seen in Figs. 9 and 14, anannular cap member 3|] which has a hub 3| keyed at 32 to the shaft 60.The hub 3| carries loosely mounted thereon the aforesaid gear 12, whichhas a hub 12A loosely mounted on hub 3|, which gear carries fixed to it,by means of suitable dowels or bolts 38, the slotted disc 33, which,upon rotation of the gear I2, may rotate freely within the annularmember 3|]. The disc 33 is one of two elements of a one-way clutch ofusual construction and has the tapered slots 34 (Fig. 14) which receivecylindrical rollers 35 whereby rotation of the gear I2 and disc 33 in acounter-clockwise direction, as viewed in Fig. 14, impartscounter-clockwise rotation to the annular member 30 and shaft 69 towhich it is' fixed, thereby rotating roll 2|. When the motor is reversedto rotate gear 12 in the opposite direction, that is clockwise 'asviewed in Fig. 14, the rollers 35 will be driven to the enlarged ends oftheir slots and roll 2| may then rotate as an idler in the samedirection as the gear 72 is then being driven and at any speed whichdoes not exceed the rotational speed of gear 12.

The gear 68 which drives gear 12, is fixed to the shaft 69 as indicatedby the spline 40' in Fig. 13. The shaft 69 has also fixed to it the gear4| meshing with the gear 42 enclosed in the swinging arm I42 of thehousing carrying the bearing I 4|, which gear 42 is fixed to the end ofthe shaft I49 with which the roll 29 is integral. Thus rotation of thegear 68 imparts rotation to the shaft 69 and gear 4| which rotates thegear 42 and drives the roll 20. The roll 20 is adapted, as abovedescribed, to be swung gradually away from the axis of spool I2 duringthe winding, but as this swinging movement is about the axis of theshaft 69 on which drive gear 4| is mounted, the gears 4| and 42 willalways remain in mesh at any position of the roll 20 about the axis ofthe shaft 69. It will be noted that no clutch mechanism is included inthe drive for roll 20. This roll is accordingly power-driven at the samerate of speed but in opposite directions for overwind and underwind.

The roll 22 is power-driven from the gear 68 (Fig. 14) through the idlergear 43 rotatably mounted on the shaft I06 infront of the aforesaidpressure gear. I05 (see also Figs. 9 and 12).

The gear 43 meshes with the gear 44 which is rotatably mounted on shaftI in front of the pressure gear 94 and is adapted to rotate the shaftHit] by a one-way clutch mechanism. The gear 44 is connected by means ofthe dowel 45 and screw 46 to a. slotted disc 4'! which, as indi-' catedin Fig. 14, has four tapered slots 48 each receiving a roller bearing49. Surrounding the slotted disc 4'! is the annular cap member 225 whichhas a, hub 226 splined at 22! to the shaft I00, on which hub 226 theaforesaid gear 44 is rotatably mounted. The opposite end of the shaftHill carries fixed to it the gear 228 which meshes with the gear 229secured to the end of the shaft 80 carrying the roll 22.

By this mechanism rotation of the gear 44 and disc 4'! in acounter-clockwise direction, as viewed in Fig. 14, imparts rotation tothe shaft Hi5 and, through the gears 228 and 229, to the roll 22 in aclockwise direction. Idle rotation of the roll 22 in a counter-clockwisedirection is permitted by its one-wayclutch mechanism when the motor isreversed and gear 44 is driven clockwise.

As stated above, my setting frame includes measuring apparatus which hasassociated with it means for providing a predetermined limited.amount'of take-off which is available to the operative for the purposeof clamping up the spool after it has been wound and for giving theinitial wrap for the next succeeding empty spool.

Referring now to Figs. '7 and 10, the measuring rolls 5 and 6, throughwhich the yarn passes from the creel 3 to the spool !2, are yieldinglypressed toward each other and are rotated by the passage of yarn betweenthe bite of the rolls. Either or both of these rolls may be providedwith suitable friction elements of the type commonly provided on suchrolls for producing a drag on the yarn and thereby tensioning the sameduringthe winding. The axis of the lower roll 6 is fixed in position andthe upper roll 5 is movable toward and away from the roll 6 and isspring-pressed in yielding engagement therewith during the windingoperation. The upper roll 5 is carried by bearings 600 which areslidably mounted in the parallel slots 55 provided in the frame members50 and 5! on each side of the machine (see Figs. Band 10) The bearingsare spring-pressed in a downward direction by means of a spring 60!disposed betweena member 688a member-600a, around which pin the spring60! is disposed. The pin 563 has an enlarged head (H2 against which theextremity 602 of the arm 6135. abuts at times to elevate the bearing69!).

The arm. 605 forms one member o'f a toggle, the other arm 60! of whichis pivoted at M3 to the arm 5B5and is secured to a shaft 608 whichextends across the machine and which, as indicated in Fig. 8, hashearings in both side frame members 5B and 5!. provided at the other endof roll 5 and the extremities of shaft 608 have secured to them the handlevers 609. If desired the shaft 608 may be a up counterweighted asindicated at 6 l0.

Both of the toggle joints 6!.3 have the usual stops against which thejoints abut when the toggle elementsa're straightened past alignmentwith eachother and in my preferred embodiment .fixed to the shaft 228.

The same toggle construction is It is apparent that rotation'of the handlever 609 in a counter-clockwise direction, as viewed in Fig. 7, breaksthe toggle joint M3 and raises the extremity 592 of the arm 605 againstthe en- I larged head 6H2 of the pin 523 connected to the memberEllilmthereby raising the same and elevating themeasuring roll 5. Whenthe parts are returned to the position indicated, by straightening thetoggle joint,. the spring-pressed button M5 is held inwardly to closethe contact in the.

switch GIS and in this position it will be noted that the measuring roll51s yieldingly urged in peripheral engagement with the fixed measuringroll 5. i

As indicated in Fig. 10, the roll 6 carries fixed to its shaft a pinion225 meshing with an idler gear 223 which in turn mesheswith a gear 22!The gear 22'! meshes with a so-called measuring gear 229 fixed to therotatabie shaft 230 to which shaft is also rigidly secured the gear 23!.The gear 23! meshes with the gear 232 which in turn meshes with the gear233. By this train of gears, feeding of the yarn through the measuringrolls 5 and 5 by means of the windingrolls 2i), 2! and. 22 causesrotation of the gears 232 and 233 in the direction indicated by arrowsand thesegears form two of the elements of'a so-called hunting toothmechanism which I employ to trip a limit switch after a predeterminedamount of yarn has been wound.

The hunting tooth apparatus is constructed as follows: The face of gear232 carries fixed to it the cam 235, (Fig. 20) having a fiat cam portionI 249, on which cam the lever 24!, pivoted at 222 is adapted to ride.The lever 24! has a reduced flange portion 236. forming a squaredshoulder struction the extension 2553 of the lever may be swung in acounter-clockwise direction about the pivot 25! but cannot move in aclockwise direction beyond a position in alignment with the lever 24!.

Extending downwardly from the extension 250 adjacent the pivot 25! is atooth 24'! adapted at times to be received by the notch 246 on a disc245, suitably secured to the face of the gear 233 and adapted to rotatetherewith. The other From the above description it is apparent that whenthe gears 232 and 233 assume the positions indicated in Fig. 20,whereinj'the fiat portionZMl on the cam 235 is uppermost, the lever 24!will be disposed in a substantially horizontal position,

thereby permitting the tooth 241 to drop into the notch 246 when thenotch arrives at the position of Fig. 20 The momentum of the notcheddisc 245, travelling in the clockwise direction indicated by .the arrow,will force theside'walls of the notch 246 against the tooth 24'! torotate the extension 25!] slightly about its pivot 25! to lift the chain252 and actuate the limit switch 253.

This operation will occur only when the rotation of gears 232 and 233bringsthe fiat portion 245 of cam 235 and the notch of disc 245uppermost at the same time and the gears .232 and 233 each i have adifferent but predetermined odd number of teeth so that this position ofthe cam and notched disc willbe assumed only once during a predeterminedmultiple of rotations of the, gears limit the counter-clockwise throwthereof.

232 and 233.

The ratio of the teeth in the gears 232 and 233 e are correlated withthe gear ratios in the gear "train leading from the gears 232 and 233 tothe measuring rolls and 6 to trip the limit switch 253 upon the passageof a predetermined yardage of yarn through the measuring rolls 5 and 6.

For the purpose of making the length of yarn measured by the huntingtooth apparatus, ad-

justable by lengths of one foot, I make the measuring roll 6 preciselyone foot in circumference and I so design the gear ratios that a changeof one tooth in one of the gears corresponds to a change of onerevolution of the measuring roll 6, that is, a change in one foot ofyarn measured. To that end the ratios of gears 225 and 221 is made oneto three and the ratios of gears 229, 23!, 232 and 233 is such that thenumber of teeth in the measuring gear 229 determines the yardage of yarnmeasured, each tooth representing one foot of yarn, so that by replacingthe gear 229 with one having, for example, one more tooth than the gear229 shown in the drawings, the yarn measured will be increased by onefoot.

For the purpose of permitting the draw-off of only a predeterminedamount of yarn, the hand lever 260 is provided. This lever is freelypivoted on the shaft 228 and carries with it a disc 26! having a camroller 262 (see also Fig. 20)

adapted to abut against and raise the roller 263 surrounding the pivot25! joining the levers 24! and 250 upon counter-clockwise rotation ofthe disc 26!,

Between the disc 26! and the gear 221, both mounted on the shaft 228,are two ratchets (see .Fig. 19) indicated at 265 and 266, secured toshaft 228. Engaging the ratchets 265 and 266 is the double ended pawl210, the end 210A 01 Q which lies in the plane of the ratchet 266 (see.also Fig. a) and is adapted to engage therewith and the end 2103of'which lies in the plane of, and is adapted to engage, the otherratchet 265. The pawl 210 is fixed .to a pivot 21! extending from disc26! to which pivot is also fixed an arm 212 connected by the link 213 tothe hand lever 214 pivotally mounted on the upper end of the lever 260.The link 213 is spring-pressed downwardly as by the spring indicated at215 so that the normal position of the pawl 210 is such that the end210A engages the'teeth of the ratchet 266 and it is apparent that withthe pawl 210 inthat position, counter-clockwise rotation of the handlever 260 will rotate the shaft 228 and gear 221 which is fixed to it,thereby rotating gear 226 and the measuring rolls 5 and 6 in a directionto feed yarn from the creel toward the spool. Such rotation is permittedas a result of the engagement of the roller 262, carried by the disc 26!(see also Fig. with the roller 263 surrounding pivot joining the levers24! and .250, thereby elevating the pivot 25! and lifting the woundspool and providing the overlap to commence the winding of the nextsucceeding spool. Upon retraction of the lever 260 against its stop 216a second tooth of the ratchet 266 will be in position to be engaged bythe end 210A of the pawl and upon a second counter-clockwise rotation ofthe lever 260 the second half of the desired amount of yarn will beunwound. The lever 260 is then returned against the stop 216 but as Iwish to provide that only a predetermined amount of yarn, measured bytwo throws of the lever 260 can be unwound by the oper- I ative, Iprovide that a thirdthrow of the lever 260 will be ineffectual to unwindmore yarn by providing that at the beginning of this throw there will beno tooth in the ratchet 266 in position to be engaged by the end 210A ofthe paw! 210. Thus it is apparent that a pair of teeth only arepositioned to be engaged by the pawl 210 during any givenunwindingoperation.

As stated aboveythe gear train leading from the measuring rolls 5 and 6to the hunting tooth apparatus mounted on the gears 232 and 233 by whichthe machine is automatically stopped, is adapted to be changed byreplacement of the measuring gear 229 to vary, in foot lengths, theamount of yarn measured by the rolls 5 and 6. It is apparent that if themeasuring gear 229 is so changed by the substitution of a gear of, say,one tooth more, the gear 221 carrying the ratchet 266, upon beingstopped automatically, will come to rest in a position different fromthat illustrated and one in which the pair of teeth which would havebeen engaged by the end 210A of the pawl 210 prior to the change wouldno longer be in the proper position for the manual unwinding.

As stated above, I provide that the ratio between the number of teeth ofthe gears 225 and 221 is in the proportion of one to three and a changeof one tooth in the measuring gear 23! corresponds to change of onerevolution of gear 225 or one-third of a revolution of the gear 221.Accordingly, I provide the ratchet 266 with three pairs of teeth (seeFig. 10b) each pair spaced equidistantly from each other around theratchet 266, and it is apparent that one of these pairs of teeth will bein positionxfor engagement by the end 210A of thepawl 210, regardless ofthe change in teeth in the measuring gear 229.

It is sometimes desirable to be able to rotate th measuring rolls 5 and6 in a direction to I unwind the yarn from the spool and in thedirection of the creel, such as when the yarn has become tangled aboutthe spool. For that purpose'the second ratchet 265 is provided withevenly spaced teeth designed to be engaged by the end 210B of the pawl210 when that end of by the lever 260.

Referring now to Fig. 21, I will describe the electric circuitsconnecting the driving motor 52 with the limit switch 253 and with'otherswitches used to start and stop the motor 52 manually and automatically.

The numerals 40!, 402-and 403 indicate power mains leading froma'suitable source of three phase sixty cycle current at 550 volts. Thesethreev phase leads are connected to a self-maintaining magneticswitch400 and thence to a reversing switch 404 from which the leads passto the motor 52. M0 indicates diagrammatically a brake adapted to stopthe rotation of the shaft of the motor 52, which brake is normallymaineueasse tained in applied position but is moved to released positionby the solenoid 4I2 connected by leads M3 and 454 to power mains 402 and40! respec lead 4532 through the lead M1 and is connected by the lead4H5, throughclosed switch BIB, to the terminal 42iiengaged'by thearmature 42! of relay 422 which is normally maintained in closedposition across terminals 42! and 423 to complete the circuit from thelead 4!8 through to'the lead 424. connected to one pole of the aforesaidlimit switch 253. The limit switch is in series with momentary contactswitch 430 by means of lead 43! connecting the limit switch to terminal432 of the switch. The pivoted switch arm 434 is normally spring-pressedto closed position against the contact 432 and the switch arm 434 isconnected by the 1ead436 to the terminal 431 disposed adjacent a switchbar 438 mounted on bar 4H5, which closes circuit between the terminal431 and a terminal 439 connested by wire 443 to lead 433. v t

The aforesaid lead .436 is also connected to a switch 442 normallyspring-pressed to open position, as indicated, but adapted to be closedacross the terminal 443 which, by the lead 444 is connected incircuit'with the'power main 433.

With the device wired as above described, a momentary closing of thestarting lever 442 closes the circuit from the wire 444 which, as aboveindicated, is connected to the power main 403,

through the starting switch lever 442 to the nor-v mally closed switch434 through the limit switch through the normally closed armature 42! ofrelay 4221?, thence through the holding coil 4!5 by means of the wire4I1,-back to the power main 4812, thereby completing the circuit throughthe coil H5, which, upon being energized, attracts switch rod M6 toclose the magnetic switch whereby to release the brakeMO and start themotor 52. The starting switch 442 may be instantly released because.a'holding circuit through the coil M5 has now been established. Thiscircuit commences at lead 442 of ,the three phase source through the,holding coil M5,,closed armature 42! of relay 422 through closed limitswitch 253, closed switch lever 434, through lead 436, and switch bar438 which is now closed across terminals 43; and 439 and thence by lead443 back to power lead 443. i

. The motor 32 continues to run until manual opening of switch lever 434of the switch 430,, or

7 until opening of the limit switch 253 or until opening'of switch ii 6,which, as above described, is adjacent the joint of the toggle which isopened upon elevation of the measuring roll 5 (see Fig. *2). These threeswitches are all in series in the above described circuit and when anyone of them is opened, it interrupts the circuit to the holding coilthereby permitting the bar M6 to move to the left, as indicated in thediagram, whereby to open the three phase switch.

The wiring circuit to my motor includes also ail-automatic stopmechanism which functions to stop the machine, in a manner now tobedescribed, upon the breaking of any of the yarns leading from thecreel to the setting frame,

As indicated in Fig. 21, I may provide, adjacent the reed 4 andbetweenit and the measuring rolls 5 and 6, a second reed 4G1 havinga rod 464extending across the machine beneath the yarn and in proximity thereto.Tothis rod 464 is pivoted a large number of switch fingers 46!, and Ipreferably provide as many fingers I 46! as there are strands of yarn lentering from' the creel to the setting frame. The end 462 of eachswitch finger 46! extends between a pair of adjacent teeth on the reed461 near the base of the teeth. The other end 453 of the switch finger,whichis the heavier end and which there-' by tends to rotate the fingerin a clockwise direction about the pivot 46!], engages'a bar 464 made ofelectrically conductingmaterial. The bar 464 extends crosswise of themachine for the full length of the reed 461 and is insulated from themachineby. a suitable insulation mounting 465.

A wire 413 connects the bar 464 in a circuit hereinafter to bedescribed.

The switch. fingers 46! are each made of elec-;

tricallyconducting material, as is the pivot rod 464 on which they arepivotally mounted and to which they are thereby electrically connected.The pivot rod 464 is carried by brackets 41! and is connected atterminal 412 to lead 415.

From the above description it is apparent that if leads 413 and 415 areconnected in an electric circuit, this circuit will be open so long asall of the fingers 46! are maintained in their elevated positions shownin Fig. 21, out of contact with bar 454. The tension in the yarn; as itis fed through the reed 461 causes depression of the ends 462 of all thefingers 46!, thereby maintaining their ends 463 out of contact with thebar 454 and keeping the circuit open. However, if any one of the strandsof the yarn! should break, during the winding, the tension on thatstrand will be released, as indicated in Fig. 22, permitting itscorrespondingswitch finger 46! to drop and close contact with the bar464 thereby closing the circuit from lead 4'!!! to lead 415'. The lead415 is connected to'the secondary 483 of a step-down transformer, whichin turn is connected, by means ofthe wire 48!, with the solenoid 482 ofa relay 433, the armature 484 of which is normally spring-pressed toopen position away from the terminals485 and 486. The circuit throughthe. coil 482 is completed by means of the wire 414 which, as abovenoted, is electrically connected to the conductor bar 464.

The primary 490 of the transformer is connected by the lead49! to the.threephase power main 492 between the magnetic switch 430 and motor 52.The other terminal of theprimary is to the wire 49! which, as abovenoted, leads tov power main 402. The other terminal 485 of relay 483 isconnected bythe wire 496 to the coil 491 of the aforesaid relay 422, thecircuit through which is completed by means of the wire 498 whichconnects to the aforesaid wire 493.

The relays 483 and 422 are both time delayed relays and are eachprovided for this purp with a dashpot of well known construction. Be-

cause of dashpot 500, the relay 483, upon being.

energized, takes a period of two seconds before complete closing of thearmature 484 across the terminals 485 and 485. The relay 422, on thecontrary, is normally maintained in closed position and when it opens,through energizing of the coil 491, it opens instantly. It is provided,however, with a dashpot 50! whereby when coil 491 is again deenergizedthe movement of the armature 42! to closed position is delayed and takesa period of ten seconds until electrical contact is made.

With the device electrically connected as above described, when themagnetic switch 400 is closed by a'momentary closing of switch arm 442of momentary contact switch 430 to start motor 52 as above described,the primary 490 of the transformer is energized by the flow of currentthrough the leads 40f and 493. At the instant of starting of rotation ofthe winding rolls 20, 2'! and 22, the strands of yarn may be quite slackwhich might permit one or more of the fingers 45! to rest in electricalcontact with the conductor bar 454 (Fig. 22). Such contact wouldcomplete a circuit through the leads 410 and 475 to the coil 482 ofrelay 483 toenergize the same and attract its armature 404. If the relay483 were adapted to close instantly, the machine would again stop as aresult of completion of the circuit through armature 484 of relay 483,from lead 49H through lead 496 tocoil 49"! of relay 422, thus attractingarmature 42! to interrupt the circuit to holding coil 4! 5 of threephase switch 400. To prevent the machine thus stopping immediately as aresult of slack in the yarn and to provide a brief time interval duringwhich the yarn may assume its taut position, I provide dashpot 500 onrelay 483 to eifect a two second delayin closing of armature 484. Thisinterval .of two seconds is suificienli tol permit the yarn to becometaut, thereby retracting the fingers 46! to their elevated positionsofFig. 21, out of contact with bar 464. This retraction of the switchfingers 46! again deenergizes the coilv 482 of relay 483 before itsarmature 484 has had time to complete the circuit, whereupon thearmature returns to its fully open position of Fig. 21. The machinecontinues to run, if not stopped by one of the switches Elli, 253 or434, until one of the strands of yarn breaks, which will again causeenergizing of coil 482 of relay 483, and, after a two second intervalduring which the finger 46! will remain in its contactingposition'ofFig. 22, coil 491 of relay 422 will be energized, thereby opening switch400 and stopping the motor.

The opening ofswitch 400 deenergizes the primary 490 of the transformerthereby instantly opening armature 484 of relay 483, and if the armatureof relay 422 also immediately returned to its closed position, theoperative could then start the machine without mending the bro-kenstrand of yarn and the machine would run for two seconds before relay484 wasagain opened. If the operative did not wish to take the pains totie in the broken strand of yarn she could make the machine continue torun by manually holding up the switch finger 40! until the broken endiscaught between the rolls and 6 when the tension of the yarn would holdthe finger 46! in its elevated position and the machine would continueto run without the broken end having been tied in. To insure againstsuch inefiicient operation and to induce her to tie the broken ends, Iprovide the dashpot 50! on the relay 422 to delay the closing of itsarmature 42! to starting position for a period of ten seconds. Theoperator can easily tie in the yarn within this inactive period and isthereby induced to do so.

While I have specified certain time intervals for the delayed actuationof the relays, obviously different time intervals can be employed ifdesired by adjustment of the dashpots inthe usual manners As statedabove and as described in connection with diagrammatic Figures 5 and 6of the drawings, in the preferred embodiment of my invention the initialwinding roll with which the yarn comes in contact for either cverwindingor underwinding, is an idle roll, the next roll is driven at apredetermined rate of speed and the last roll is driven slightly morerapidly. For some purposes it may be desirable to make the initial roll,in either the overwinding or underwinding direction of rotation, adriven roll and I have provided a modification of my preferredembodiment in which the initial roll is a driven roll, the second rollis driven at a rate of speed slightly greater than that of the initialroll, and the third roll is driven at a rate of rotation slightlygreater than that of the second roll in the series. As will appear froma detailed description of my modification, this relationship ispreserved for either the overwinding or underwinding directions ofrotation.

Fig. 23 of the drawings is a view illustrating such modification andcorresponds to Fig. 9 of the drawings of the preferred embodiment of myinvention. The pinion 10A corresponds to the pinion ":0 of Fig. 9 and ismounted on the drive shaft of a reversible electric motor connected inan electric circuit identical with that described in connection withFigs. 21 and 22. The pinion lllA'meshes with a large gear 530 which isfixed on-a shaft 53!. The shaft 53! carries splined to it the gears 502and 503, which gears are cast on-the same hub, indicated at 504, whichhub, with the gears 502 .and 503, may be slid longitudinally of theshaft 53! and for that purpose is grooved at 505 to receive trunnions505 mounted on the ends of a bifurcated member 50'! on the end of arm508 fixed on the end of shaft 509 which is suitably supported adjacentthe frame of the machineand provided with a shifting hand lever 5|0rigidly secured to the upper end of the rod 559 and adapted to rotatethe same. By this mechanism it is apparent that shifting of the handlever 5! 0 will shift gears 502 and 503 from their positions indicatedin Fig. 24 in which the gear 503 is in mesh with a gear 5! and the gear502 is not in mesh with any gear, to a position wherein the gear 503 isout of mesh and the gear 502 meshes with a gear 5|2.

The gears 5!! and 5!2 are secured to a shaft 5!3 to which is secured theroll 2!, which roll, as in my preferred embodiment, is mounted in fixedbearings (see Fig. 15).

The aforesaid shaft 53! which is rotated by the gear 530 fixed to it,like the shaft 59 (Fig. 9) of the preferred embodiment of my apparatus,carries fixed to it a gear 4IA, corresponding to gear 4! (Fig, 13) ofthe apparatus of my preferred embodiment, by means of which roll 20 isrotated. This roll, as in my preferred embodiment, is mounted in amovable bearing adapted, by pressure gears, to swing about the axis ofth'eshaft 53L The gears 502 and 583 at times mesh respectively withidlers 526 and HI mounted onsuitable" stud shafts, which idlers in turnmesh respectively with gears 522 and523 which, as shown in Fig. 25, aresecured to the shaft 524 rotatably mounted in the frame of the machine.The shaft 524 corresponds to the shaft IENB (Fig. 12) 'of my preferredembodiment andcarries the gear 228A,

by means of which the winding roll. 22 is driven, the said winding rollbeing mounted, as before, on a shaft which has a bearing adapted toswing about the axis of the shaft 524 toward and away from the spoolduring the winding operation.

The swinging of the rolls 2i and 22 toward and from the spool beingwound, is eiiected in my modified embodiment in the samemanner as in,tliepreferred embodiment, namely, by a set of a leading from a pressuregears '(not shown) pneumatic source of power. I With the modificationconstructed as above described, the motor is rotated to drive the pinionliiA in the desired direction, depending upon whether overwinding orunderwinding is desired.

22 rotate at a certain predetermined rate of speed, the second roll 29rotate at a speed slightly greaterthan that of the roll 22, and the roll2| ,be driven at a speed slightly greater than that of the roll 26. Forthis purpose the gears 502 and W3 are disposed in the. position in whichthey are shown-in Fig. 24, by movement of the hand lever 5H3 ifnecessary, in which case the gear 563 meshes with the gear 5!! and alsowith idler 52! which,fin turn, drives gear 523which rotates the roll 22.Gear 523 has a greater number of teeth than gear 503, which latter gearin turn has a greater number of teeth thangear 51! which results in amoderate rotation. of roll 22, a slightly faster rotation of roll 28 anda still faster rotation of roll 2i, as is. desired for the overwindingor counter-clockwise direction ofrotation of the winding rolls. Y

In the underwinding direction of rotation the rolls 20, 2| and 22 eachrotates clockwise by a reversal of direction of the motor which drivesthe pinion A, which is now also made to rotate clockwise.

rotates faster than the roll 20, the hand lever 510 is shifted until thegear 503 comes out of mesh with the gear 5 and idler 521, and the gear592 meshes with the gear M2 and with idler 526. It will be noted thatthis shifting of the gears 502 and 563 on shaft 531 does not changethespe'ed of roll which rotates at the same speed both clockwise andcounter-clockwise, determined partly by the ratio of pinion WA and gearm; The speed of rotation of roll 21 is, however, decreased relative tothe speed of roll 20 and the speed of roll 22 increased relative to thespeed of rotation of roll 25 by this shifting of the hand lever 5H3,because gear 5H2 has a greater number of teeth than gear 502 and thegear- W2 in turn has a greater number of teeth,

i is rotated through meshing of the gear 592 with I perform either orboth of those functions.

In this direc- To produce the desired 'ratio of speeds, namely, that inwhich the roll 29 rotates faster than the roll'2l and the roll 22 inturn idler 520. r

In this manner all of the rolls are made powerdriven in both theoverwinding and underwinding directions in my modified embodiment andthe desired ratio of speeds to produce tensioning of the yarn. adjacentthe spool is preserved regardless of direction of rotation. I

Qbviouslymypreferred embodiment is subject I Q to other modificationswithin the spirit of my invention which is to be limited only asindicated by the appended claims. Thus, although I have mined speeds forrotating the receiver and also I for swinging the rolls toapply'pressure to the receiver or spool being wound, Ido not wish tolimit myself to, such mechanism but can obviously employ othermechanism, suchas belt drives to Nor is the predetermined speed at whicheach of the power-driven rolls is rotated necessarily a con- .stantspeed but may be a variable predetermined speed effecting anincreaseddiiferential of speed between the winding rolls as the spoolfills whereby to increase the tension onthe yarn and thereby counteractthe increased tendencytoward pufliness which may obtain after aconsiderable amount of yarn has been wound on the spool.

Obviously hydraulic, electrical or any means other than thepneumatically operated apparatus described maybe employed for, exertingthe yielding pressure of the swinging winding rolls against the spooland for removing the top roll to replace the wound spool with an emptyone,

provided the means chosen effects a yielding pressure which may begradually applied and of any desired amount.

winding operation. For an effective winding operation it is notessential that the rolls assume this position at the very beginning ofthe winding operation because at that time the periphery of thespoolwith one or two layers of yarn is rela- ..tively small and propertensioning of the yarn does not require equal spacing of the rollsthroughout currently herewith, I may wish to direct the yarn in astraight line path from the guide roll l I, tangentially of the spoolwithout being deflected by roll 2| during underwinding, or by roll 22during .50 that small distance. vAs described in detail in my copendingapplication Serial No. 45,839 filed conoverwindin which may be moreconveniently accomplished by spacing the rolls .2! and 22 widely apartand' not equidistant relative to each other and to roll 20 during theinitial winding rotation.
